Abstract
A process for deactivating a hydrocarbyl phosphonium salt catalyst in an epoxy resin fusion reaction by contacting with a sulphonic acid, such as p-toluenesulphonic acid or methane sulphonic acid. The process is particularly suited for deactivation of moisture-resistant phosphonium salts such as methylene bis(triphenyl phosphonium halide)s.
